Outcome: a real landed-cost-per-unit figure to price your product against, not a rough guess.

  1. Open ChatGPT or Claude.
  2. Give it your product cost, shipping cost, insurance, duty rate, and any other fees.
  3. Ask it to calculate the total landed cost per unit.
  4. Double-check the duty rate against your actual customs tariff schedule, don’t trust an AI-guessed rate for the final number.

Sample prompt: Calculate my landed cost per unit: product cost $[x], shipping $[x], insurance $[x], duty rate [x]%, other fees $[x]. Show the full breakdown.

Pro tip: Save this calculation as a template, you’ll reuse the same structure for every new product line.
